UNITED STATES JAMES C. LYNCH, OF HARRISON, NEV JERSEY.

BAG-HINGE STAY.

SPECIFICATION forming part of Letters Application filed June B, NSS.

To aZZ whom, it may concern:

Beit known that I, JAMES C. LYNCH, acitizen of the United States,residing at Harrison, in the county of Hudson and State of New Jer- 5sey, have invented certain new and useful Improvements in BagIIingeStays; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which 1o it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

The purpose of this invention is to provide abag-hinge stay which is ofsimple and strong construction; and it consists of the ordinary hingeapplied to bag-frames, having a supplementary hinge or hingedlocking-arm pivotally attached to one of the hinged plates or leaves ofthe main hinge, and which is adapted to be turned into holdingengagement with a stop or iiat surface on the main hinge-joint, thusholding open the mouth of the bag until released from such engagement.The devices which have heretofore been used for this purpose, havingsupplementary hinges, have been of such construction as to be verydifficult to manipulate the same, particularly when the parts were notWell fitted.

My improved device is designed to remedy this difficulty and to providea hinge-stay which can be secured to the bag-frame with comparativelylittle labor, and which can be made economically.

In the accompanying sheet of drawings, in which similar letters ofreference are used to indicate corresponding parts in each of the views,Figure l is a plan of an opened bagframe and the hinge-stay in itslocked position. Fig. 2 is a similar but enlarged view of the hinge inits unlocked position. Fig. 3 is an end elevation of' Fig. 2. Figs. 4and 5 are a plan and an end elevation, respectively, of the hinge in itslocked position; and Fig. 6 is a section taken through line x, Fig. 2.Figs. 7 and 8 are plan views of another form of hingestay in itsunlocked and locked position, respectively. Fig. 9 is a side elevationof the device shown in Fig. 8, and Fig. l0 is a side 5o elevation of ahinge having a modied form of Patent NQ. 390,609, dated October 2, 1888.

Serial No.276,498. (No model.)

sists of two portions, the main hinge A and the supplementary hinge orhinged lockingarm B. The hinge portions orleaves a and a ofthe mainhinge A are adapted to be riveted or secured in any convenient manner tothe ends of the frame-sections C and C' of the bag. The hinge portion orleaf a is provided with hinge-joints or ears a2 a2, to which ispivotally secured said locking arm B by means of the pin b.

To cause the locking engagement of the hinged locking-arm B with thehinge-joint of thehingeA,thelockingarm,whichisindicated in the drawingsby the letter b', is turned on its pivotal pin b", causing the end b2 ofthe arm b to come into engagement with the flat surface a of thehinge-joint of the hinge A, thus locking the same and causing theholding open of the mouth of the bag.

To manipulate the hinged locking-arm* B more easily, a finger-piece, b3,is secured thereon in any suitable manner. As indicated in Fig. 6, thejoint part of the hinged lockingarm B is provided with asharp corner oredge, b5, on its under side, which rests against the hinge-plate a andholds said hinge in a horizontal position when unlocked and prevents thesame from hanging down within the mouth of the bag, substantially asindicated in said Fig. 6.

The construction shown in Figs. 7, 8, and 9 is of such form that the armb is formed of one straight piece, instead of curved, as shown in Fig.l, et seq., and is provided with a projecting finger on the end, asshown. In said lastnamed views, as a modification, the hingejoints orears a2 a? may be placedat a point farther away from the main joint ofthe hinge A, as will be understood from the drawings. Said joints a2 a2may also be placed on either of the hinge-plates a and a', or the earsa2 may be formed on the hinge-plate or leaf d and engage With the hingeIjoint on the leaf a, as will be understood.

The hinge-joint shown in Fig. 10 may be formed with an additional fiatsurface, a4, which enables the operator to lock the hinge at a smallangle; or said joint may be provided with any number of such fiatsurfaces, which enables the operator to hold open the frame sections ofthe bag at any convenient angle, asis evident.

IOO

By the form of locking device thus set forth there is no danger ofpinching the fingers, as is common in the locking devices most con1nionly used in operating the same. Therefore,

Having thus described my invention, what I claim is" 1. A bag-hingeprovided with an arm pivotally secured to one of the leaves thereof andadapted and arranged to be turned into and from engagement with a flatsurface formed on the rounded outside ofthe eye of the other leaf ofsaid hinge at thejoint thereof, for the purposes set forth.

2. A hinge consisting of the portions a and a', one of which, a, has alocking-arm, B, pivotally attached thereto, said locking-arm beingadapted to engage with a fiat surface, a3, on the joint of the portion ato lock said hinge, substantially as and for the purposes set forth.

3. lIhe combination, with the frame sections of a bag, of the hinge A,consisting of the hinged portions a and a', one of which, a, is providedwith ears a, the other of which, a, is provided with a flattenedsurface, a3, at the joint, and an L-shaped locking-arm pivoted to saidears and adapt ed to engage with said dat surface a and lock said hingewhen open, substantially as and for the purposes set forth.

4. A hinge consisting of the hinged portions a and a', one of which, a,is provided with ears a2, the other of which, a', is provided with aflattened surface, a, at the joint thereof, and a lockingarni pivoted tosaid ears and adapted to be turned into and from engagement with saiddat surface formed on the joint of the other leaf, 'for the purposes setforth.

5. The combination, with the frame-sections of a bag-frame and hingedleaves or plates secured to said sections forming the bag-hinge, one ofsaid leaves having a stop on the eye thereof, of a bag-hinge stayconsisting of an arm pivoted to one of said hinged plates and engagingwith the stop on the eye of the other hinged plate to lock the hingewhen turned for that purpose, as set forth.

In testimony that I claini the invention set forth above I have hereuntoset my hand this 6th day of June, 1888.
